Delta printer work in progress

Update posted as separate thing: http://www.thingiverse.com/thing:387134
This is my work in progress (perhaps excessively robust) delta printer design. Most parts are in version 1, although I've designed a little more than I've posted so far and have the majority of the construction sitting on my desk for development purposes. I will add to this post as I refine the design.
Note: the currently posted models are not intended for 3D printing (and half the parts are missing anyway!). These models have been bundled into blocks to be used in OpenSCAD for animation only. Once I'm happy with a sufficient number of the parts to actually make a printer to this design, I'll post individual files and instructions. The files posted are actually my inverse kinematics test for my unconventional delta printer joints in the form of an OpenSCAD animation.
I will add to this thing as I have working parts, so if interested, keep an eye out.
